What is oral blister?

Oral blisters are small appendages or protrusions that usually appear as fluid-filled sacs or surface sores inside the mouth, on the tongue, lips, gums, or roof of the mouth. These blisters can be clear, white, yellow, or red in color and are often accompanied by pain, burning, or discomfort when eating, drinking, or talking.

Blistering in the mouth is usually a sign of inflammation or the body's reaction to external factors, such as an unwanted bite, food allergies, or the use of certain medications. Some blisters will heal on their own within a few days without the need for specific treatment, but in some cases they may be a sign of underlying diseases or viral infections that require further investigation. Understanding the nature of this complication is the first step to choose the right treatment method and prevent its recurrence.

You can see an example of a mouth blister photo in the image below.

Types of mouth and lip blisters

types of mouth ulcers and blisters may have different appearance, location and causes. Some of them are viral, some are caused by immune system reactions, and some are caused by nutritional deficiencies or underlying diseases. Knowing the type of blister and the main cause of its occurrence plays an important role in choosing the appropriate treatment method and preventing the recurrence of blisters and ulcers.

In the following, you will learn about the most common types of blisters and oral lesions:

oral blister due to herpes

cold sores is a viral infection caused by the herpes simplex virus (HSV-1) that causes small, painful fluid-filled blisters on the lips and around the mouth. These blisters are contagious and are transmitted through close contact. Cold sores are often associated with burning, fever and feeling tired for no reason.

Anemia

In people with anemia, especially anemia caused by iron deficiency, the oral mucosa becomes weak and vulnerable, and they may face oral lesions in the form of ulcers or blisters. This condition can also be accompanied by a burning sensation of the tongue. Anemia has other symptoms such as paleness, cold skin, pale gums, lightheadedness, dizziness, increase or decrease in blood pressure, fatigue and heart palpitations.

oral blister due to gingivomatitis

Gingivomatitis is an inflammation of the gums and oral mucosa that is often seen in young children and is accompanied by painful blisters (especially when eating), salivation, fever and bad breath. These blisters have a red center and a yellow or gray border. The cause of this type of oral blister is a viral infection, especially the herpes virus.

Infectious mononucleosis

This viral disease, also known as "kissing disease", can cause inflammation of the throat, enlarged lymph nodes, blisters, sores or bumps in the mouth. The cause of this disease is Epstein-Barr virus (EBV) and its recovery may take up to 2 months. Infectious mononucleosis is more common in teenagers and young adults.

Canker wound

Cancer is a kind of painless skin wound that usually occurs in the early stages of syphilis. These sores appear inside the mouth, on the lips of the genitals or the anus (where syphilis bacteria enter the body) and at first they seem harmless. The small red bumps of canker sores quickly fester (turn white or yellow) and become larger and become sores.

However, these sores will disappear after four to eight weeks without treatment, but untreated syphilis can lead to serious damage to the heart and brain. Canker sores can indicate other dangerous diseases such as Crohn's disease, celiac disease, vitamin deficiency or AIDS.

Folate deficiency

Folate (vitamin B9) plays an important role in the health of the oral mucosa. Deficiency of this vitamin can lead to painful sores and blisters on the mouth, tongue or gums. Weakness, pale skin, fatigue, swollen tongue, gray hair and delayed growth are other symptoms of folate deficiency in the body.

Thrush of the mouth

It is a type of fungal infection caused by Candida albicans, which is often seen in babies, children and people with a weak immune system or after taking antibiotics. Oral thrush is associated with white or cream-colored spots on the tongue, gums, and roof of the mouth, and sometimes ends in inflammation and blisters. Oral thrush causes other complications such as pain in the area of the bumps, loss of sense of taste, problems in swallowing, dry and cracked skin in the corners of the mouth.

Leukoplakia

It appears as thick lesions, white spots and sometimes rough and hairy, on the oral mucosa. This complication is usually painless, but with constant irritation, it may turn into a sore or blister. Leukoplakia is more common in smokers and usually improves after two weeks. If leukoplakia persists, further investigations should be done for precancerous changes and risk of oral cancer.

Lecan plan

It is a type of chronic autoimmune disease that can cause lesions in the form of white or red spots and lines and superficial ulcers and blisters (white lace-like spots) in the mouth. These blisters, which often involve the sides of the tongue, the inside of the cheek, and on the gums, are associated with pain, itching or burning, but they are not contagious and do not have the risk of becoming cancerous.

There is no quick and immediate treatment for this ulcer on the side of the tongue and dentists usually prescribe mouthwash and the use of ointments and tablets to relieve the pain and discomfort. Diagnosis of lichen planus is done by a dentist and clinical examinations and sampling of the wound.

Celiac disease

In people with celiac disease (a digestive disease caused by gluten sensitivity), consuming gluten (a type of protein found in wheat, barley, and rye) may lead to an immune reaction in the body and complications such as blisters and sores in the mouth, especially on the tongue and cheeks.

Black hairy tongue

It is a rare and safe condition in which the bumps on the surface of the tongue turn black or brown and have a hairy appearance. This condition is sometimes associated with discomfort, burning and an unpleasant metallic taste in the mouth.

Antibiotic use, poor oral hygiene, lack of oral saliva, smoking, drinking too much tea and coffee are among the causes of black hairy tongue. Brushing the tongue and using a tongue scraper is the best treatment for this condition, but taking medicine is also necessary.

mouth disease

One of the most common types of mouth blisters is oral thrush. The plague usually appears as a round or oval wound with a red border and a white or yellow center that appears spontaneously and heals within one to two weeks without the need for treatment. These wounds are seen on the tongue, cheek and gums.

Geographic language

Geographical tongue is a benign complication that changes the color and shape of the language surface, so that the language looks like a map. Spots and blisters can change their size, pattern and location within minutes to hours.

Some patients experience pain, burning or irritation when eating certain foods. This disease is usually not dangerous, but if there is pain, taking over-the-counter painkillers and anti-inflammatory drugs will help you.

Amalgam tattoo

Gray or black spots that are caused by contact with dental filling materials (such as amalgam) in oral tissues. Penetration of pigments and silver contained in amalgam into oral tissues may look like a sore or blister, but it is not painful and does not require treatment.

If the amalgam tattoo grows or changes color, you should suspect the type of oral wound and visit a dentist for further investigation.

Gingivitis

It is one of the types of gum diseases which is caused by the accumulation of bacterial plaque. This condition is associated with swelling, bleeding, sensitivity and pain in the gums, and in more advanced stages, it leads to ulcers or mouth blisters.

Periodontitis

It is an advanced form of gingivitis that occurs by ignoring the inflammation and bleeding of the gums. This disease causes the decay of the gums and tooth-supporting tissues. In severe cases, sores or blisters may develop in the gums that require specialized treatment.

External factors that cause mouth blisters

Some types of oral blisters are caused by internal diseases or infections, but sometimes external and environmental factors irritate the oral mucosa and cause blisters. Knowing these factors helps to prevent and treat wounds better:

• Mechanical injuries such as accidentally biting the tongue or cheek while chewing food or talking
• Collision of sharp and hard objects with the tongue
• stimulation caused by artificial teeth or orthodontics
• Burns with hot food or drink
• Allergic reaction to toothpaste or mouthwash containing compounds such as sodium lauryl sulfate
• Allergy to certain foods such as nuts, chocolate, citrus fruits or spicy, acidic and spicy foods
• Mental stress and immune system weakness caused by stress and nervous tension
• use of tobacco or alcohol
• Non-observance of oral and dental hygiene and the formation of bacterial plaques
